SPECIFICATION forming part of Letters Patent No. 791,477, dated June 6,1905.

Application filed October 18,1900. Renewed November 8, 1904. Serial No.231,954.

To aZZ whom it may concern:

Be it known that I, WILLIAM A. LATHROP, of Wilkesbarre, in the countyof-Luzerne, and in the State of Pennsylvania, have invented certain newand useful Improvements in Car- Dumps; and I .do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, in which I Figure 1 is a sideelevation of my car-dump, and Fig. 2 is, a transverse sectional viewthereof.

Letters of like name and kind refer .to like parts in each of thefigures.

The object of my invention has been to provide a car-dump by which thecontents of a loaded car can be readily transferred to a receptacletherefor or other place of discharge; and to such ends my inventionconsists in the car-dump hereinafter specified.

In carrying my invention into practice I provide a framework A,consisting of posts or uprights a; and a, upon which are supported uppercross-beams a and a, that carry upper stringers a and a and lowercross-beams a and a which carrylower stringers a and a Intermediatecross-beams a and a are also supported by the posts or uprights a and a,and such cross beams carry intermediate stringers a and a. The upper andintermediate stringers which support the rails extend from the rear sideof the framework only part way across the same. Rails B and B extendalong the upper stringers a and a and are then curved down and back andextend for a short distance along the intermediate stringers a and a.From the intermediate stringers the rails B and B are curved down andforward to meet the lower-stringers a and a, along which they pass tocarry the car away from the dump. There is thus in efiect an upper and alower track connected by an S-shape track. Guard-rails C and O extendparallel to the S-shapeportions of the rails B and B and at a distancetherefrom equal to the diameter of the car-wheels, such guardrails beingsupported by braces c and 0, secured to the rails B and B.

A vertical apron D extends down the forward posts a and a from the upperstringers to its normal position.

to a'point where it meets an inclined apron E, and the latter extendsdownward and rearward until it meets a double chute F, which is bridgedover the rails B and B and extends downward on each side thereof.

In the operation of my car-dump the car, propelled in any desiredmanner, is run along the upper straight portions of the rails B and Buntil it reaches the curved portions thereof, where are also theguard-rails G and O. The car then descends the curved portions of therails B and B and the guard-rails, the car being gradually overturned bysuch action and its contents thrown against the aprons and into thechute until at the portions of such rails which are attached to theintermediate stringers the car is completely inverted and entirelyemptied into the chute. The car then passes down the remaining curvedportions of the rails, and thus becomes restored The chute beingelevated above the rails B and Ballows the car to pass thereunder andalong the portions of the rails B and B which extend along the lowerstringers.

Changes which donot involve a departure from the scope of my inventionmay be made.

For instance, it is manifest that during the rearward portions of thetravel of the care'. 6., from the forward portion of the upper bend tothe rearward portion of the lower bend-the weight of the car is*on theguardrails. If desired, the rails B and B can be omitted along theportions where the weight of the car is on the guard-rails, and theguardrails can be omitted along the remaining curved portions of therails B and B..

Having thus described my invention, what I claim is 1. The combinationof two substantially horizontal tracks, in a higher and a lower plane,respectively, and a vertical compound, curve connecting said tracks, oneportion of which is substantially horizontal, such portion being belowthe upper track and above the lower track, wherebya car in traversingsaid curve is inverted.

2. The combination with two substantially horizontal tracks,in a higherand a lower plane, respectively, connected by a vertical compound curve,one portion of which is substantially horizontal; such portionbeingbelow the upper track and above the lowertrack, whereby a car intraversing said curve is inverted, of a car having a plurality of-wheelsin a single plane, adapted to run on said tracks and curve..

3. The combination with two substantially horizontal tracks,in a higherand a lower plane, respectively, connected by a vertical cornpoundcurve, one portion of which is substantiallyv horizontal, of. aear.havingva plue rality of wheels in a single plane, adapted to run on saidtracks andcurve, sueh'cur-ve-acting to invert said car, thus dischargingits contents.

6.

7.
